I don't get how the installer made its own partition, it doesn't make partitions, it just installs. Did you maybe use Disk Utility to format the disk and chose 2 partitions.

The disk must be partitioned using the GUID Partition Scheme to install and use Windows or to be able to use Boot Camp Assistant to partition or un-partition the drive. Open disk Utility, choose the disk, (not just a partition) on the bottom right where it says Partition Scheme it must be GUID. If it's not you must erase and reformat the drive to make it GUID.

On reflection I think I invoked Time Machine and it created the second partition. All I want to do is get rid of the second Time machine Backup partition and put the space back in my primary disk. Then I want to use boot camp to create a partition for Windows XP.

Hmm, Time Machine won't create partitions. Not sure what you did.

Do what I mentioned in the last paragraph above, what partition scheme is the hard drive?

The boot camp assistant is what creates partitions (or disk utility if you did an erase/partition/install) ...try opening up the boot camp assistant again and see if you have the option to remove the partition.

Time machine should not be used on a partition. It needs to be used on a second internal HD or an external HD. Otherwise if the one drive dies your backups go with it.

From what I read above it sounds like you kinda have the two things mixed up. Boot Camp is for Windows ...Time Machine is simply for OS X backups.

2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. Otherwise, click on the Partition tab in the DU main window.

3. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled, if supported.) Click on the Partition button and wait until the volume(s) mount on the Desktop.

4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.

5. Set the format type to Mac OS Extended (Journaled, if supported.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.

6. Click on the Erase button. The format process will take 30 minutes to an hour or more depending upon the drive size.

Steps 4-6 are optional but should be used on a drive that has never been formatted before, if the format type is not Mac OS Extended, if the partition scheme has been changed, or if a different operating system (not OS X) has been installed on the drive.

you can delete the Tiger partition using partition tab in disk utility. select the partition and click on "-". If this partition is the LOWER of the two partitions when viewed from disk utility you can grab the lower right end of the upper leopard partition and drag it down to reclaim the free space left by the deleted partition. click "apply" afterwards. If the deleted partition is the UPPER partition you can not absorb it into the other partition without reformatting the whole drive. in that case, since you have a TM backup you can boot from the leopard install DVD, start disk utility on it and reformat the whole drive using partition tab. then quit disk utility and select "restore system from backup" from the utilities menu. follow the instructions.

I gave you detailed instructions, and asked some questions as to how you have your system configured, what machine it is etc, but you didn't answer them. It's all needed to know how to solve your problem. Do what I suggested and report back.
